Three Signs You Need To Replace Your Sump Pump

Posted on

Sump pumps are a common basement waterproofing method that are used to pump water that has begun to rise before it has the chance to actually enter your home and do damage to your belongings. Just like all other appliances, however, sump pumps have a set lifespan and can begin to malfunction or break entirely after enough use and time. Understanding some of the signs associated with an old and worn out sump pump can help you determine when you should begin thinking about replacing your current unit.


One of the most common signs that your sump pump has reached the end of its life is if you notice that it is constantly turning on and off. This can be because of a damaged mechanical component but can also be because of faulty wiring within the unit itself. A sump pump that constantly turns on and off will quickly wear out the motor and other parts within the pump, making a complete failure during a heavy storm much more likely – not to mention driving up your monthly utility bills.

Grinding and Irregular Sounds

Another clear sign that your sump pump may no longer be operating as it should be is if you notice that the sounds that it creates when it turns on are irregular or take on the sound of grinding or other sounds of excessive friction. This can point to physical damage that is causing parts to rub against each other that shouldn't be, which can cause a complete pump failure at a later date.

Corrosion and Mold Growth

Additionally, there are a pair of signs associated with age and infrequent use that can quickly render your sump pump inoperable. Rust and visible corrosion on the metal parts of your pump will prevent your sump pump from actually pumping water out of the reservoir, which can lead to pumping. In severe cases, rust can actually eat its way through entire components, leaving your sump pump dead in the water. A sump pump that has not turned on in a while can allow mold to grow in the reservoir as well. This growth can actually get so thick that it clogs the motor, fan and other moving parts of your sump pump. You can't simply clean mold out, since it is a safety hazard to handle, so you should get in touch with a contractor about either cleaning out your sump pump or replacing it entirely.
